UNITED STATES PATENT OFFICE GEORGE W. BROWER, OF SANTA MONICA, CALIFORNIA.

' SUSPENDED RAILWAY.

To alt whom it may concern:

Be it known that I, GEORGE W. BROWER, residing at Santa Monica, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Suspended Railways, of which the following is a specification.

My invention relates to certain new and useful improvements in suspended railways, and it particularly seeks to provide a railway of this character of a very simple and economical construction which can be easily and cheaply operated and can be used along the right of Wa of telegraph-lines and can run alongside 0 the telegra h-poles.

My invention also inc udes means whereby the car is enabled to turn short curves with the greatest ease, and means are also provided whereby the car can be run with the greatest freedom from jar and vibration and with the least possible noise. Generically, my invention includes a sus pended railway, the cars of which include suitable trucks, each of which trucks comprises main driving and supporting wheels, a pair of pilot-whee s at the ont and rear of the drive-wheels, and means for shifting the pilot-wheels so that only one set is in operation at a time. A air of fixed retainingwheels, one at each si e of the drive-wheel, cooperate with the driver-wheels.

My invention also includes a novel means for mountin the drive-motor to the truck, so that it and the driving-gear will move with the truck on its pivot-axis, so as to alwa s maintain theproper alinement between t e drive-motor and the drive-wheel.

My invention also includes a novel arrangement for pendently mounting the carbody, whereby the rails or overhead support can be conveniently connected to the ordinary type of telegraph-poles and in such manner that the weightof the car, the trucks, and the drive-motor are balanced to provide for a smooth and safe travel of the car on its trackway.

The manner in which the front and rear trucks are correlatively arranged and combined with the drive-motor, the drive-wheel,

and the retaining and guide wheels also forms an'essential feature of my present invention, as does also the manner in which the motor devices are. geared up with the drivewheel; and the means for providing for the Specification of Letters Patent. Application filed January 31, 1906- Serial No. 298,779.

cross-section of the car Patented April 24, 1906.

automatic lateral adjustment of the motor and the gear connections that join with the drive-wheel and the combined arrangement of the motor and the manner of sustaining it on the drive-truck, as before intimated.

My invention also comprises a novel construction of running-gear including a truck having a main frame, a vertically-dis osed master-wheel'supported in said main ame for traveling on top of the up er or main rail, a pair of fixed retaining-whee s rotatable in a plane at right angles to the drive-wheel with their axis of rotation in the same vertical plane with the axis of rotation of the drivewheel, and a supplemental frame oscillatably supported by the main frame and carryin at the front and rear ends thereof a air of pi otwheels, one wheel of each pair adiipted to engage one side of the main track, while the other wheel of the same pair engages the other side of the main track, and means connected with the supplemental frame for oscillating the same way, so that only one pair of pilot-wheels (the pair in advance of the driver) will be in operative engagement with main track at a time. The truck also includes a special form of turn-table, whereby the same can be pivotally connected with the car-body to turn on a vertical axis at right an les to the pivotal axis of the drive-wheel an lying in t e same plane with such drivewheel pivotal axis. In addition to the foreoing the truck also includes a novel platform extension for supporting the drive-motor and having means cooperating with the supporting-trackway on the car-body for taking up the weight of the motor and serving to aid in its support.

With other objects in view than I have heretofore enumerated my invention also embodies a novel construction, combination, and arran ement of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawin s, in which %igure 1 is a perspective view showing my invention as a plied for use. Fig. 2 is a cross-section of the trackway, showing the general arrangement thereof and the general arrangement of the cars on the same when my lnvention is used along the right of way Fig.3 isan enlarged of the telegraph-lines.

and a portion of its trnckway, taken on a plane approximately through the pivot-axis of the drive-wheel and the retaining wheel-axis; Fig. 4 is a crosssection on the line 4 4 of Fig. 3 looking in the direction of the arrow. Fig. 5 is a horizontal section on the line 5 5 of Fig. 4 looking in the direction of the arrow. Flg. 6 is a perspective view of the front or motor truck. Fig. 7 is a similar view of the rear truck. Fi 8 is a perspective view of the supplemental ame detached. Fig. 9 is a view of a modified form of truck hereinafter specifically referred to. Fig. 10 is a diagrammatic side elevation of a modified form of my invention. Fig. 11 is a dia rammatic view on the line 11 11 of Fig. 10 ooking in the direction ofthe arrow.

Fig. 12 is a diagrammatic cross-section showing how the trestle-work and track structure may be arranged for city use. Fig. 13 is a similar view showing how the telegraph-poles may be used as supports for the trestle-Work. Fig. 14 is a detail diagrammatic view of a modified form of magnetic brake mechanism for use in connection with my system, and Fig. 15 is a detail view hereinafter specifically referred to. Fig. 16 is a modification hereinafter referred to.

Referring now to the accompanying drawings, in which like reference numerals and letters indicate like parts in all of the figures, 1 designates the main supporting-posts of the trestlework, to which the cross-arms 2 2 and 3 3 are secured by bolts 4 and 5 or otherwise, as may be found desirable, brace rods 6 being also provided for the usual functions.

Secured to the cross-arms 2 2 are the lower guide-rails 7 7, while the upper guide, and

traction rails 8 8 are secured to the arms 3 3,.

as shown, suitable spacing-blocks 9 and 10 being provided to raise the rails above the cross-arms. The upper or traction rail 8 projects slightly beyond the spacing-block 10, as at 8 for a purpose presently explained.

The car 11 is supported upon front and back trucks 12 and 13, of like construction with the exception that the front or motor truck carries the drive-motor 14, as shown in detail in 6.

In the form of my invention shown in Fi s. 1, 2, 3, and 4 there is but one motor-trugk, although I desire it understood that both the forward and rear trucks may be made as motor-trucks when desired, as shown in the modified form of my invention in Fi 9.

Referring now more particul arly to Figs. 3, 4, 5, and 6., it will be seen the motor-truck 12 comprises a main supporting-frame consisting of the turn-table 12, having a ballrace 12 in its upper face and a second ballrace' 12 on its under face to receive bearingballs 12, as shown. A suitable bearing-- plate 15, having a ball-race 15 issecured to the cross-brace 11 of the car-body by bolts 16, as shown, and the bolts 16 serve to secure a ring 17, having a ball-race 17 a to cooperate secured to the members 25 with the lower bearing-balls 12*, as shown clearly in Fi s. 3 and 4. A king-bolt 18 may be provide for ivotally connecting the turn-table 12 tot fully without the use of the king-bolt 18. Projecting downwardly from the tum-table is a pair of arms 12 12 which have bearin s 12 12 to su port and receive the main drive-shaft 19, w ch carries the drive-wheel e plate 15, if desired, although the turn-table will operate success- 20, hereinafter again referred to. The downwardly-projecting arms 12 12 terminate in rearwardlyextending horizontal arms 12 12 to which the motor-platform 14 is bolted or otherwise secured, as shown. The main shaft 19 at one end carries a sprocketwheel 22, over which and over a sprocketwheel 14 on the motor 14 an endless chain 14 passes, whereby the action of the motor 14 will be imparted to the shaft 19 to turn the drive-wheel 20. The drive-Wheel 20 in my invention is provided with a pneumatic tire 21, as shown, or the same may be a cushion tire, if found desirable, serves to give an easy smooth riding to the car and avoids all unnecessary vibration and jolting and also permits me to use wooden traclr'ways 8 in ace of metallic tracks, and hence reduces t e cost of construction considerably. The motor-truck also includes asupplemental frame 25, 'arallel arms 25 25,

crumed'at 24 to the downwardly-project- 'Eg arms 12 of the turn-table 12 and-the crums 24. The king-pin 18 and the main and this tire 21 which comprises the which are centrally ioo drive-shaft 19 lie in the same transverse vertical plane for a purpose presently more clearlyunderstood. The supplemental frame j has its parallel members 25 25 connected together at their free ends by U -shaped connecting-straps 26 26, which are firmly in any desired manner, and the straps 26 have laterallyprojecting feet 26, which have bearings 26 to receive the spindles 26 upon which the pilot-wheels 27 are pivotally held. The pilot-wheels 27, it will be seen, are four in number and arranged in pairs, one to the front .and the other to the rear of the turntable of the main frame, and the pilot-wheels 27 are spaced apart so that they will bear against the sides of the track 8 when they are in their operating positions, as will be more fully understood presently. On the main drive-shaft 19 I also secure a brake-drum 30, around which a brake-strap 31 takes, and the brake-strap 31 is secured at one end to one of the downwardly-proj ecting arms 12 and has its other end connected with the plunger 32 of a magnetic brake-magnet 33, which may be bolted directly to the motor-casing, as

is an arm 28, which carries at its upper end a wheel 29, provided with pneumatic or cushion tires 29 and rotatable on a shaft 29 in the arm 28. The wheel 29 rides on a trackway 34 on an arc of a circle having its center on an axial line passing throu h the kingbolt 18 of the tum-table, .and t e trackway 34 is secured by a bracket portion 34* to the supporting-beam. 11 of the car-body, as clearly shown in Fig. 4. The car-body 11 is also provided with vertical sup orting-beams 11 11 to which bearing-brac ets 35 are secured, and the bearing-brackets 35 have bearings to receive the bearing-bolts 35*, upon which a retaining-Wheel 36, having pneumatic or cushion tires 36*,is mounted and arranged to engage the side of the track 8, as clearly shown in Fig. 3, and this wheel forms one of what I shall hereinafter term the stationary retaining-wheels to distinguish them from the shiftable pilot-wheels. The axis of rotation of the wheel 36 lies in the same transverse vertical plane as the axis of rotation of the main drive-wheel 20 and the ivot-axis of the truck which passes through t e kin -bolt 18. Op osite the fixed retaining-whee 36 is a second fixed retaining-wheel 37 having a tire 37 ofsimilar form to that 36 of the wheel 36, and the second fixed retaining-wheel 37 is mounted on a s indle 38*, secured in the bracket 38, that is astened to the car-body beams 11. The axis of rotation of the wheel 37 and thatof the wheel 36 and that of the king-bolt 18 lie in the same vertical transverse plane at all times and in the same vertical transverse plane as the axis of the drivewheelwhenthe parts are in the position shown in Figs.- 3 and 4 and the car is running straight ahead. The wheel 37 enga es the side of the track opposite that engaged by the wheel 36, and the arrangement of the wheels 36 37 and the drive-wheel 20 are such that at all times the points of contact of the three wheels just mentioned will lie in the same vertical plane as the axis of rotation of the fixed retainingwheels and the axis of rotation of the turntable. The pilot-wheels 27 are also provided with pneumatic or cushion tires 27 The supplemental frame 25 is oscillatable on its pivots 24 by means of the vertically-extendmg arm 39, which is secured to one of the bars 25 by any desired means and to the upper end of which the shiftin -rod 50 is ivotally secured. The rear true 13 is of ike construction to the front truck 12, with the exception that it only contains the turn-table 13 havingthe ball-races 13 and 13, corresponding to those on the forward truck, and the downwardly-projecting arms 13 13 having bearing portions 13, in which the main shaft 19 is held. The rear su porting or drive wheel'20 is mounted on t e shaft 19 as shown. The wheel 20 has a pneumatic tire 21 similar to that on' the front drive-wheel. A supplemental frame 25 is pivotally secured at 24 to the downwardlyprojecting arms 13 13 of the rear truck 13 and is of the same construction as the front supplemental frame, the shifting-rod 50 connecting the two supplementa frames toether, so that the can be shifted inunison' respectively, which are also provided with pneumatic or cushion tires 54 55, and the said wheels 54 55 are arranged in the same horizontal lane and bear a ainst opposite sides of the ower track 7, as c early shown in Fig. 3. 58 designates a pair of bracket members secured to the car-body, which carry the trolley-wheels 59 59, that bear against the trolley-wires 60, mounted on insulators 61 on brackets 62, projecting from the main columns 1 of the trestle-work.

So far as described the manner in which my invention operates will be best understood by reference to Fi s. 1, 2, 3, 4, and 5 of the drawings, from whi h a will be Seen that when the cars are running in the direction of the arrow in Fig. 4 the operating-rod 50, which controls the supplemental frame 25, is shifted in the direction in which the car is going to move the supplemental frames to the position shown in Fig. 4, so that the front pair of pilot-wheels are in operative engagement with the track-rail 8 and rotatable in the same horizontal plane with the fixed retaining-wheels 36 37, while the rear pilotwheels of each truck are u out of engagement with the track, as shown. This en- .ables shorter turns to be made by my railway than would be possible were all four pilot-wheels of the supplemental-frame simultaneously in engagement with the track and also insures the ositive turning of the turn-table to always ee the driver-wheels directed in proper vertioa alinement with the track, since the forward pilot-wheels shift the turn-table immediately as the drive-wheel enters the turn and in proportion to the arc of the curve in the rail. As the turn-table is shifted on its pivot-axis the motor 14 and all the other carrled parts of the turn-table will likewise be shifted, the wheel 29 running upon its track 34 to relieve the truck of the excess wei ht of the motor. Thus the motor will be shi ed from the central alinement to one side or the other, depending upon the direction in which the car is turning. This is essential, since were the motor stationary with respect to the car-body and shiftable with respect to the drive-axis of the truck it would be impossible to obtain a satisfactory gearin between the motor ,and the drive shaftfiiut by arranging the parts as shown clearly in Fig. 6 of the drawm s the motorshaft and the drive-shaft are a ways in parallel alinement. with one another and the driveinions of the motor and drive shaft will a ways be in the same alinement, and thus the drive-chain will. be pro erly maintained thereon, and the motor W1 1 easily op- 5 erate to drive the car. -Now assume it it desired'to reverse the direction of movement of the car. It is only necessary to shift the rod 50 in the direction opposite to the arrow in Fig. 4, when the rear pilot-wheels will be brou ht into enga ement with the track 8 and i he forward pi ot-wheels lifted up out of engagement therewith. The motorman can then reverse his current and reverse the direction of travel of the car andbe assured that the drive-wheels will be always maintained in their pro er alinement with the track by the pilot-w eels in advance thereof. In Fig. 9 I have shown a slightly-modified form of my invention, in which there are two motor-trucks employed of like construction, and in Fig. 9 I have shown also an additional modification of my invention in that in this form the means for shifting the front and rear ilot-wheels is somewhat different. In this orm of my invention the downwardly-projecting arms 12 12 of the turn-table have front and rear extensions 12 12 terminating in bearings 12 to receive longitudinallyshiftable spindles 26 which ca the pilotwheels 27, and its-shafts are shifted alternately in pairs through the medium of the oscillatm' lever 65, which is linked to the shafts 26 at t eir upper ends by the links 66, which are pivotally secured to the levers 65 and to the shafts 26", as shown. The levers 65 have upwardlyprojecting lever-arms 65 which are operatively connected together by the shift-rod 50, as shown, so that the levers 65 of the front and rear trucks can be simultaneously operated in the same manner as for the form shown in Figs. 1, 2, 3, and 4 of the drawin s. a a

In Figs. and 11 I have shown a still further modification of my invention, in which the front and rear trucks are ivoted together, as at 70, and in which 0 y one set of pilot-wheels 27 is provided for each truck, since in this form of my invention the front and rear trucks operate as one, the one set of pilot-wheels of the one truck sufficing to shift reference to the drawings. In this form "of my invention the pilot-wheels are shifted.

lever will he s ed in the direction of the running at a high rate 0 s eedI project the both trucks, as will be clearly understood by arrow to tighten the brake-band around the In Fig.15 I have shown the universal connection between the shifting-rod 50 and the lever that operates the. oscillating su plemental frame 25, by reference to whicli figure it will be seen' that the goint comprises the link 80, which is'fulcrume at 81 to the collar 82, that is loosely held on the operating-lever, as shown.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation, and many advantages of my inven- 4 tion will be readily understood by those 8o skilled in the art to which it appertains, and it will be also seen that by providing the various supportin -wheels, retaining-wheels, pilot-whee s, an drivewheels, &c., with pneumatic or cushion tires I am enabled to obtain an easy smooth running of the car and am also enabled to construct the tracks of wood instead of metal, thus eatly reducing the cost of construction of t e system.

This system is particularly adapted for use in cities as well as in countries, and when my invention is used in cities the trackway can be constructed, as shown diagrammatically in Fig. 12, so that the cars will run alongside of the telegraph-poles, and thus not take u unnecessary room in the street. Again, I may utilize the telegraph-poles as supports for the track structure, as shown in.Fig-. 13.

By use of my railway system a very high rate of speed may be attained, as the ilotwheels will positively guide-the drive-w eels on the track and-keep them always in pro er alinement, so that they will not run 06, an to insure the car from jum ing the track when rob 10 free ends 35 of the brac et' 35 under the 5 track 8, as clearly shown in Fig. 3, and my system can be used alo the right of way of telegraph-lines, thus avoiding the necessity of a special right of way and reducing the .cost of installation. Again, my system is particularly advantageous in countries of desert land as well as in rocky districts, as it is unnecessary to make deepand ex ensive cuts through the rocky districts, an the danger of sand drifts over the tracks now so common in surface lineson desert land is avoided.

In Fig. 16 I have shown a slightly-modified form of my invention in which the means engaging the under side of the track-rail or for preventing the car from jum ing the tracks consists of a small wheel held in a bracketv 91, secured to the car-body, as shown. I also desire it understood that while I have shown an electric. motor. for the driving power I IIO -may use any other suitable motor in place of main driver-wheels should the tires become punctured, I place wheels 200, mounted on axles 130, in front of the trucks, as shown.
